WASHING-MACHINE.

Specification of Letters Patent.

Patented Nov. 24, 1914.

Application filed July 17, 1914. Serial No. 851,535.

To all whom it may concern: r

Be it known that I, WVrLLIAM O. BUNKER, a citizen of the United States, residing at Nevada, in the county of Vernon and State of Missouri, have invented a new and useful l/Vashing-Machine, of which the following.

is a specification.

The present invention appertains to washing machines, and aims to provide a clothes washer of novel and improved construction which embodies in combination with the rocking tub or receptacle, a unique oscillatory beater therein, for efficiently and conveniently cleansing the clothes.

It is also within the scope of the present invention toprovide a clothes washer of comparatively simple and inexpensive construction, which will be convenient, practical, serviceable and efficient in its use.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein Figure 1 is a vertical longitudinal section of the improved washing machine, taken on the line 1-1 of Fig. 2. Fig. 2 is a vertical transverse section of the machine taken on the line 2-2 of Fig. 1.

In carrying out the present invention, there is employed a rectangular receptacle or box 1, of any suitable construction, which is trunnioned or mounted for oscillatory movement between the upper ends of a pair of standards 2 which have a suitable base for supporting them. The receptacle or tub 1 is provided with a suitable handle 3, for convenience in rocking or oscillating the receptacle in theoperation of the machine. The top of the receptacle 1 is also provided with an opening 4 and, a cover 5 is hinged to the top of the receptacle to normally close the opening 4 and to permit access to be had to the interior of the receptacle. leg 6 is hinged to one end of the receptacle 1, so that it may be swung outwardly as indicated in dotted lines in Fig. 1, to rest upon the floor for holding the receptacle stationary while being filled or emptied. When the receptacle 1 is tobe rocked, the leg 6 may be swung upwardly against the corresponding end of the receptacle, and may be held in folded or idle position by means of a suitable latch7 pivoted to the end of the receptacle.

Coming to the salient or cardinal features of the present invention, which resides iii the provision of an oscillatory beater head within the receptacle 1,.the said beater c'olir prises triangular end pieces 9, a yoke or head board 10 secured to the upper edges of the end pieces 9, and a series of cross slats or strips 11 secured to the side ed es of the end pieces 9. The beater Sis tins in the form of a chamber triangular-in-ciioss section having slatted sides, the slats being,

spaced to form slots therebetween, whereby the slots establish communication frorritlie i terior of the beater to the exterior thereo; The slats 11 are of triangular cross section, as seen in Fig. 1, to provide downwardly facing shoulders and the upwa ds extending faces, the lower edges of the slats or strips 11 being, relatively wide, while their upper edges are relatively sharp or narrow. Between the lower corners or ends of the end pieces 9, is secured a cross bar 12.

In order to mount the heater 8 for oscillatory movement within the receptacle 1, straps or strips 15 are secured to the lower ends of the end pieces 9 and are pivoted upon the pintles 14 of bearing plates 15 secured to the inner faces of the sides of the receptacle 1 intermediate the ends of the receptacle and adjacent the bottom thereof.

Thus,the beater 8 has its lower portion 111".

crumed or pivoted to the tub adjacent the bottom thereof and intermediate the ends of the tub, in order that the beater may swing to either side of a vertical position, or be yond the dead center toward either end of the tub. The Weight of the beater will therefore tend to swing it toward one end or the other of the tub, as the tub or receptacle is rocked.

In use, to fill the tub, the cover or lid 5 is swung open and the beater is swung toward one end of the receptacle or tub 1, and a quantity of clothes is then placed between tpe heater and the other end of the receptac e. last mentioned end of the receptacle, and a similar quantity of clothes are placed on the opposite side of the beater. The cover 5 is The beater is then swung toward the a then closed and latched in closed position, in which event, the receptacle 1 may be rocked to clean the clothes, it being understood that the wash water has been previously poured into the tub. It will also be obvious, that the clothes at the opposite ends of the tub, or on the opposite sides of the beater 8, tend to counter-balance each other, to render the oscillation of the receptacle most convenient. As the tub or receptacle is rocked, the clothes will alternately tend to move from one end of the receptacle to the other, whereby the beater will be similarly moved, to greatly assist in the cleansing action. For example, supposing the clothes be applied in the receptacle 1 as seen in Fig. 1, then, when the receptacle 1 is rocked or tilted. toward the left, the beater 8 would be swung toward the left assisted by the mo mentum of the clothes at the right hand side of the beater, and as a result, the clothes at the left hand side of the beater would be squeezed, and furthermore, the left hand slats 11 in engaging the clothes would rub and engage the same in a peculiar manner to assist in the cleansing action. The beater in oscillating within the receptacle, will also cause the wash water to be forced between the slats 11, whereby the wash water would be forced through the clothes simultaneously with the squeezing and rubbing action thereof. A similar action ensues when the receptacle is swung toward the right as seen in Fig. 1, so that it will be evident that when the receptacle is rocked, the clothes will be thoroughly agitated and cleansed. The beater 8 is over-balanced, so that the rocking of the receptacles forcibly throws the beater from one end of the tub toward the other, which in connection with the momentum of the clothes and wash water, will carry out the desired results.

The present machine subjects the clothes to the least amount of injurious rubbing, and carries out the cleansing action in a simple and thoroughly eifective manner.

Having thus described the invention, what is claimed as new is In a washing machine, a rocking receptacle, and a beater therein, comprising triangular end pieces having certain corners pivoted to the receptacle adjacent the bottom and intermediate the ends thereof, spaced slats secured to the side edges of the end pieces, the upperjedges of the slats being relatively sharp and the lower edges being relatively wide, and a head board secured to the upper-edges of the end pieces.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in, the presence of two witnesses.
